Contramar (Durango 200, in Roma, tel. 5514-9217 or 5514-3169, lunch only, 1–6 p.m. daily, entrées $10–25) serves outstanding seafood in a bright, airy dining room bustling with waiters attending the 20-odd tables. Start off with the delicious tacos de camarón ($7), stuffed with minced shrimp and more reminiscent of an Asian-style spring roll than a taco, then move on to the succulent filete Contramar ($20), served on a wooden platter and lightly coated with sauce.
